A little package proposal question

Dear scsh users,

i installed your package library on my computer
with scsh version 0.6.6. I used the scsh layout
and the directory /usr/local/share/scsh/.
After that i put that path into the SCSH_LIB_DIRS
variable.
When i try to use an installed package as sunterlib
i get the following error message:
Error Illegal path element in SCSH_LIB_DIRS
$SCSH_LIB_DIRS: /usr/local/share/scsh/
The following element is not a string or #f: /usr/local/share/scsh/

Maybe you can help me with that problem.

Greetings
